A method of creating electromagnetic interference includes creating an electromagnetic (EM) field of a frequency at distant target by transmitting at least two electromagnetic beams. At the target, the beams may converge and interfere creating an interference difference frequency. In another method, the beams may be combined and the combined beams create an interference over a distance. An interference difference frequency is selected so that a desired electromagnetic frequency is established at the target creating interference. The interference difference frequency is established by the difference in the two electromagnetic beams. As each converges or is combined, the resultant frequency corresponds to the difference between each the frequencies of each beam. An apparatus for creating electromagnetic radiation includes at least two transmitters. The transmitters permit directing the electromagnetic beams in directions permitting either convergence of the beams or combination of the beams, thus creating electromagnetic interference.
